Standards and how to choose
Specifying thermals correctly means matching the product to the right EN standard. These guides explain what the ratings mean, in plain English:
- Embroidery vs Print for Workwear: Which Should You Choose?Branding your workwear comes down to two main methods — embroidery and print. Each suits different garments, designs and budgets. Here is how to choose.
- GORE-TEX® vs Standard Waterproof Workwear: Is It Worth It?For people outdoors all day in the rain, usually yes. For occasional use, usually no. Here is how GORE-TEX® Workwear compares with PU-coated and breathable waterproofs, with real prices from our range.
- How to Wash GORE-TEX® Workwear (Jackets & Trousers)Washing doesn’t harm a GORE-TEX® Garment. Dirt does. Here is Gore’s own care routine for GORE-TEX® workwear, with the extra checks that hi-vis and rail garments need.
- EN 343 Explained: Waterproof Workwear Classes4:4:R, 3:1 or 3:3? The EN 343 label on a waterproof tells you how well it keeps rain out and how well it lets sweat out. Here is how to read it.
